Construct an equation for the complete combustion of an unsaturated alcohol with 5 carbon atoms and one double bond.

The solubility of pentan-1-ol and pentane-1,5-diol in water is shown below:

• Pentan-1-ol: 22 g dm^-3
• Pentane-1,5-diol: infinitely miscible

Explain the difference in solubility between pentan-1-ol and pentane-1,5-diol.

Butan-1-ol can be oxidised to form two different organic products, depending on the reaction conditions used.

Describe both oxidation reactions of butan-1-ol. For each reaction include:

• the structure of the organic product
• a balanced equation
• the essential reaction conditions.

In your equations you may use $[O]$ to represent the oxidising agent.
